Topography, vegetation cover and below ground biomass of spatially constrained and unconstrained foredunes in New Jersey, USA

摘要

Space for dunes is often limited in developed areas, placing increased importance on human efforts to aid dune-building. This study assesses how different management strategies influence dune topography, surface cover and below ground biomass of vegetation on four dune segments in New Jersey in two successive years. Two segments are evolving without human actions, one with a cover of native vegetation (Ammophila breviligulata) and one with an invasive exotic (Carex kobomugi). Two segments are in developed areas and are maintained using sand fences, vegetation plantings and bulldozers; one of these segments uses bulldozers to bury a seawall.
